25 Questions

1. The precision of a number resulting from measurement depends upon

2. Can never be more precise than the least precise number in the calculation.

3. Common fractions are changed to percent by flrst expressmg them as

4. To change a decimal to percent multiply the decimal by 100 and annex the percent sign (%). Since multiplying by 100 has the effect of moving the decimal point two places to the right - the rule is sometimes stated as follows:

5. The more precise numbers are all rounded to the precision of the

6. How much to round off must be decided in terms of

7. Deals with the group of decimal fractions whose denominators are 100-that is fractions of two decimal places.

8. Can be a significant digit if it is not the first digit in the number because it is a part of the number specifying how many hundredths are in the measurement.

9. Before adding or subtracting approximate numbers - they should be

10. The accuracy of a measurement is often described in terms of the number of

11. It is important to realize that precision refers to

12. Closely associated with the study of decimals is a measuring instrument known as a micrometer.

13. The maximum probable error is

14. To add or subtract numbers of different orders

15. A larger number of decimal places means a smaller

16. There are three cases that usually arise in dealing with percentage - as follows:

17. It is possible to round off a repeating decimal at any desired point - the degree of precision desired should be determined and:

18. The maximum probable error is found when the denominator of the fraction expressing the error ratio is divided into the numerator or

19. The probable error in any measurement is how precisely the instrument is marked - The precision of a measurement depends upon

20. In a number such as 49.30 inches - it is reasonable to assume that the 0 in the hundredths place would not have been recorded at all if it were not a

21. To find the percentage of a number - multiply the base by the rate. The rate must be changed from a percent to a decimal before multiplying can be done.

22. Percent is used in discussing

23. To flnd the bue when the rate and percentage are known

24. A rule that is often used states that the significant digits in a number

25. The extra digit protects the answer from
